Precautions for Use
Caution
Install an emergency stop circuit on the outside to immediately stop operation if necessary.
Reset the alarm when the servo is off. Be warned that the system restarts immediately if the
alarm is reset while the servo is on.
Minimize electromagnetic interference by using a noise filter or DC reactor. Otherwise, adjacent
electrical devices may malfunction because of the interference.
Use only the specified combinations of servo drive and servo motor.
The electric brake on the servo motor keeps the motor at a standstill. Do not use it for ordinary
braking.
The electric brake may not function properly depending on the brake lifespan and mechanical
structure (for example, if the ball screw and servo motor are combined via the timing belt).
Install an emergency stop device to ensure mechanical safety.
Malfunction Precautions
Caution
For potentially dangerous situations that may occur during emergency stop or device
malfunction, use a servo motor with an electric brake, or separately install a brake system on
the outside.
In case of an alarm, solve the source of the problem. After you solve the problem and ensure
safety, deactivate the alarm and start operation again.
Do not get close to the machine until the problem is solved.
Precautions for Repair/Inspection
Caution
Before performing servicing tasks, turn off the power. Wait 15 minutes until the charge lamp
goes off, and then check the voltage. Voltage may remain in the condenser even after you turn
off power and may cause an electric shock.
Only authorized personnel are permitted to perform repair, inspection or replacement of parts.
Do not modify the product.
